SPECIFICATION forming part of Letters Patent No. 370,298, dated September 20, 1887.

Application filed November 12, 1886. Serial No. 2l ,74O.

To aZZ whom, it may concern:

Be it known that we, WILLIAM N.\VHITELEY and \VILLIAM BAYLEY, citizens of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Grain- Harvestersnan1ely,Improved Driving-Gearing-of which the following is such a full, clear, and exact description as will enable any person skilled in the art to construct and use the same, reference being had to the accompanying drawings, forming a part of this specification.

Our invention relates to grain-binding harvesters, and is in the nature of improvements upon the usual form of construction and arrangement thereof.

It consists in so constructing the main driving-gearing that the transverse counter-shaft shall have a journal on each side of the pinion which engages the main driving-gear fixed to the main wheel. For this purpose the main driving gear is an independent spur gearwheel, so located that the inside line of the face is far enough from the line of the rim of the main driving and supporting wheel to admit of a journal-box being located between them. It is usual to use a gear-wheel either fixed .to or cast upon the main driving and supporting wheel and placing the pinion engagingtherewith upon the end of the transverse countershaft,with no supporting journal-box beyond it, thus supporting the said shaft only upon one side of the pinion. By this construction the friction and wear upon the inner journalbox was found in practice to be excessive, and hence theimproved form of construction herein described was devised;

In the drawings, Figure l is a perspective view of a harvester embodying our improvements. Fig. 2 is a side elevation of the main frame, gearing, 810. Fig. 3 is a plan of the same. Fig. 4 is a sideview of the relief-rakes; and Fig. 5 is a side view of a portion of the elevator, showing the device for throwing the machine into and out of gear. Figs. 6, 7, and 8 are diagrams illustrating the position of the lower elevatorroller in relation to the cutting apparatus.

Similar letters refer to like parts in the several views.

(No model.)

A, A A and A are thesills composing the main frame, to which the main driving and supporting wheel 13 is journaled in the journal-boxes b and b by the main shaft a, in the usual manner.

The draft-tongue T is pivoted to the sill A, and controlled in its relation to the main frame in any convenient manner.

Fixed uponthe main-wheel shaft is the spur gear-wheel O, which drives the bevelpinion F through the pinions D and E, runningloose upon the crank-shaft c, and connected therewith, when desired,by the clutch f, sliding on a splined portion of the shaft e, the bev'etpinion F having a half-clutch formed upon it at f. The olutchf is in the form of a sleeve,upon which is formed the oollarf, against which presses the fork g, which is pivoted to the right-angled lever G,which in turn is pivoted to the main frame or a fixed part thereof at 9 The shipper-rod h extends from the lever G to the shipping-lever H, which is pivoted to the elevator apparatus, as shown in Fig. 5, and by which the machine is thrown into and out of gear. When in gear,the shipping-lever takes the position shown by dotted lines. The clutch f is heldin gear by the springf and out of gear by the shipping-lever H,passing over the center, as shown in Fig. 5.

The crank-shaft e is journaled in the boxes 6 6 and c, fixed t0 the main frame, and has fixed upon it the crank-disk z',by the wrist-pin of which the cutter-bar is driven by a pitmanrod, as usual, the sprocket-wheelj, by which .the binder is driven, and the sprocket-wheel 70, by which the elevator-rollers K K, the reel, (not shown,) and the relief-rakes L L are driven.

The transverse counter-shaft d is journaled in the boxes d and dflboth formed on one piece fixed to the sill A of the main frame and supported by the brace d, extending diagonally across to the rear sill, A, of the main frame. The function of the brace d" is to furnish a firm support for the box d as far removed as possible,in order to prevent a torsional strain upon the sill A of the main frame. By this construction we are also enabled to furnish the counter-shaft d with a bearing in the box at beyond the spur-pinion D, whereby the great strain and friction of an overhanging pinion is in a great measure relieved and the crankshaft e, with its parts, brought nearer to the main driving-wheel B.

Referring to Fig. l, J is the binder-deck. K is the elevator sides. M is the grain-platform. W is the divider.

Upon the lower elevator-roller shaft is fixed the bevel gear-wheel N, which engages the bevel gear-wheel O, fixed upon the shaft n, which is supported at this end by a bracket fixed to the elevator side K and at the opposite end by the bracket n, fixed to the reelstandard P. Upon this end of the shaft 12 is fixed the spur-pinion Q, which engages the spur-pinion It, fixed upon the crank-shaft 1", also journaled in the bracket n and provided with the cranks tt. i

- Pivoted upon the cranks t t are the two relief rakes L L, which are guided and held in their proper place by the rods Z Z, pivoted to the centers of the relief-rakes at one end and to the seat-board V at the other. The reliefrakes are provided at their lower ends with the forked and curved iron plate Z as usual.

The motion communicated from the elevator-roller shaft, through the medium of the gears N O Q R and shafts n r to the cranks t t,

operates the reliefrakes L L, whose lower ends move in an elliptical path, as shown by dotted lines in Fig. 4, and in direction of the arrow, their movement resembling that 01 a human hand grasping the grain, grass, or other clogging matter, and pulling it forcibly away from the inner shoe; and as the reliefrakes engage the clogging matter alternately, there is no opportunity for it to accumulate.

In Letters Patent No. 239,004, issued to W. N. Whiteley, a single relief-rake, like one of the rakes L, is shown and described; but in using a single rake it frequently happens that in the interval during which the rake is not acting upon the grain some grain will pass by and not be affected by the rake. Itis impracticable to increase the speed of the rake, because it would then strike and scatter the grain instead of pushing it gently. We therefore add another rake and make their motions alternate with each other, so that practically the action is continuous.

By providing the two relief-rakes, whereby the clogging of the elevator-belt is avoided, it becomes practical to make the elevatorbelt the same width as the platform'belt, as before stated. The lower roller, k, of the elevator belt may therefore be placed on a level with the inner roller, of the platformbelt, as shown in end elevation in Fig. 6, in plan in Fig. 7, and in side elevation in Fig. 8, the roller it being placed in the angle of the finger-bar so, instead of running above it, as it must necessarily do if the elevator-belt were wider than the platform-belt. The position of the lower elevator-roller, 7c, in case of a wide elevator-belt, is shown in dotted lines in Fig. 6, by which the advantage of its location as low as possible will be at once perceived, as in the case of its location as shown by dotted lines there is much more opportunity for short grain to drop through the space between the elevatorbelt and platform belt to the ground.

Having thus described our invention, its construction, arrangement, and uses, and pointed out wherein our devices differ from those usually employed for the purposes.

sought to be accomplished, what we claim as new, and desire to secure by Letters Patent, 1s-

In the main driving-gearing of a harvester, the transverse counter-shaft (1, having upon it the main pinion D, the two boxes (1 d one on each side of said pinion, whichengages the main gear-wheel fixed to the main driving and supporting wheel, the said boxes being formed on one piece of cast metal, fixed to the main frame and projecting inwardly therefrom, said inwardly-projecting part being provided with a seat adapted to be secured to and supported by diagonal brace d, fixed to the side and rear sills of the main frame, substantially in the manner and for the purposes shown and described.
